Silicone sealant five selected features

Requires sealant has a low modulus, high displacement capability, better with wood properties, freely scalable, best to use 50LM (50 low modulus magnitude) silicone sealant. The displacement capacity of plus or minus 50%. Skylights with plastic also requires transparency is good, nice, especially in high-rise and high-rise curtain wall, Oita panes of glass curtain wall, using laminated insulating glass curtain wall, seismic fortification area 9 degrees on the wall, even in these types of situations combination, but also need to use high-performance structural silicone sealant. Silicone sealant tensile strength and elongation at break are high, with the same bonding width can withstand greater loads.

Most silicone sealants are named according to the site of application, when used also by the selection of the appropriate parts of silicone sealant.

1, building curtain panel seams. Building walls between the panel and the panel joints need glue to fill, then you should use silicone weather sealant. It needs to withstand the wind load, dynamic load, the deformation of the substrate caused by thermal expansion and contraction displacement, while in the case of tension or compression, adhesion will not be destroyed, but also has good elastic recovery rate, the displacement of the panel disappears, it can return to its original state. Refer to the standard "glass curtain wall joint sealants."

2, light top position. Skylights due to their own weight load, snow load, wind load, asymmetric load and deflection caused by thermal expansion material large and complex, not only horizontal displacement, and shear displacement. Particularly the use of a polycarbonate plate, due to its high coefficient of thermal expansion and contraction, the glass 67 times.
3, structural silicone sealant assembly parts. And its supporting structure in the curtain wall panel sealant used between the need to withstand a variety of loads, and to ensure long-term adhesion, not fall off, you must meet national mandatory standards "structural silicone sealant" (GB16776) requirements .
4, the area between the doors and windows. Colored aluminum windows and doors aluminum and glass to use the gap between room temperature curable sealant fill. Fully cured, integrally formed between the glass and aluminum.
5, stone panel area. Stone panel components must be used exclusively stone silicone sealant. Because the stone itself is a porous material, susceptible to contamination, and contamination is difficult to remove. General sealants containing plasticizers and other non-reactive low molecular weight substances, internal migration from the gum to the stone house, the stone surface of the oil and dust, causing the stone pollution. This adhesive is divided into two categories. First stone sealing glue for security seals caulk between the stone plates.

The second is hanging stone with plastic, stone and metal hook for the bond between. Past used stone hanging rigid class epoxy glue, building vibration, they will pass the stress stone panel, stone easily be shattered. In the past with polyacrylates, neoprene, polyurethane filling, adhesive or easily damaged by external force, or harmful volatile gases. Silicone sealant no such ills, can play a long tamper seals, waterproof effect.
